BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to a device for protecting the ears of the user, and more particularly to a lightweight ear protection device that is supported by the ears and protects the ears from the elements while facilitating the user's ability to hear.

2. Description of Related Art

Conventionally, ear muffs and the like have been provided with ear pieces at each end of a headband, with the ear pieces then being worn with the headband put around the top of the head or around the base of the head region of the head. FIG. 1 shows an example a known headband that wraps around the back of the head. Here, the article 10 comprises two ear pieces 16 (with only one being shown in FIG. 1) and a headband 14 clamping the ear pieces 16 at each end to the user's head 12. The headband 14 is constructed of flexible material, for example, a plastic spring material, to provide resilience.

The article 10 is put on the user's head 12 by slightly broadening the space between the ear pieces 16 at the ends of the headband 14 so that the ear pieces 16 are brought in position adjacent the ears 11. When the article 10 is put onto the head 12, it is positioned in such a manner that the ear pieces are pressed onto the user's head 12 and ears 11 by the resilience of the headband 14. In this way, the ears become sandwiched between the head 12 and the ear pieces 16. At the same time, the middle of the headband 14 comes into contact with the neck or collar of the wearer at the base 15 of the head region 20 of the user's head 12.

When this article 10 is used as described above, the ear pieces 16 are pressed to the head 12 as a result of the resilience of the headband 14. However, this structure does not enable active support by the ears 11 because its means of support is tension from the resilient material. In some designs it can be partially supported by the middle part of the headband 14 coming into contact with or riding on the base 15 of the user's head region 20 or the neck 19 or collar 21 at the side of the base 15 of the head region 20.

Unfortunately, when, for example, the headband 14 comes into contact with the neck 19 or collar 21 of the user's clothes, movement of the user's head 12 generates stress in the headband 14, thus stressing the entire structure. As a result, the position of the article 10 is frequently changed, causing noise and discomfort, which affects an individual's ability to concentrate and hear. In addition, the resilience of the tensioned headband 14 forms a sealed cup around the ears, interfering with sound entering into the ear canal. Because there is no active ear support feature, the resilience in the headband 14 must be strong enough to prevent the ear protection device 10 from falling off the head 12, causing unnecessary pressure to be exerted on the ears and the head 12, which can cause discomfort to the user. This discomfort is compounded when the level of sound the user can hear from beneath the ear pieces 16 is diminished. Thus, despite the existence of various types of earmuffs and headbands, there remains a need for an ear protection device having the advantages of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring initially to FIG. 2, shown therein is a side view illustration of a first embodiment of the ear protection device 18 formed in accordance with the present invention. The device 18, shown on the head 12 of a user, has ear protectors 23 connected to or integrally formed with a headband 22 that positions the ear protectors 23 adjacent to and in alignment with the ears (not shown in this view) of the user.

As shown more clearly in FIG. 3, the device 18 includes outer ear frames 26 that are either connected to the frame 22 by an interlocking joint 24 or are integrally formed therewith and inner ear cups 28 attached to the ear frames 26. The headband 22 is formed to have a semi-flat, elliptical shape, which in one embodiment connects to the outer ear frame 26 through the interlocking joint 24. The joint 24 includes connectors 40 and 42. The interlocking joint 24 is secured when the connectors 40 and 42 are fused together through a process such as gluing or sonic welding.

The headband frame 22 is formed in a curved shape to fit the shape of a typical individual's head, and more particularly to fit the shape of the base 15 of the head region 20 of an individual's head 12. The overall shape of the headband 22 is approximately that of an omega (Ω). As shown in FIG. 2, the headband frame 22 is formed to curve in a lower direction overall so as to approximately run along the lower ends of ears, known commonly as the lobe of the ears. More particularly, the headband 22 is sized and shaped to extend downward below the user's earlobe when worn by the user and to extend behind the user's head 12 to leave an unobstructed space adjacent the top of the user's ear to accommodate the use of headgear such as glasses, hats and helmets.

Referring to FIGS. 3-8, the ear frame 26 is formed to have a concave-shaped outer wall 38 that is, in this embodiment, substantially semi-circular in nature. It is to be understood that the shape can be other than semi-circular. This built in concave shape is aerodynamically designed so that moving air is directed around the outer wall 38 of the ear protection device 18 rather than directed toward the user's ear. The ear cups 28 are formed with semi-rigid material in a generally spherical configuration, with each ear cup 28 having a concave inside surface 29 and a convex outside surface 31. The ear cups 28 are formed of suitable materials to create comfortable warmth and protection for the ears such as fabric or soft moldable components such as plastic or silicone.

In one embodiment a material, such as fabric, is used to form ear pads 60. As shown in FIG. 6, the ear pad 60 is sized and shaped to stretch over, attach to, and cover each ear cup 28. As shown therein, the ear pad 60 has an elastic ring 62 formed on one side that slips over the ear cup 28. By design, the ear pads 60 require minimal fabric and therefore reduce the amount of fabric and related sewing required for construction.

The ear pads 60 include a component to support the device 18 on the top of the ear. As shown in FIG. 6, the component comprises an ear pocket 64 that is formed along a portion of the ear pad 60 to have an opening 66 sized and shaped to slide over the top of the user's ear. When so positioned, the pocket 64 supports the device 18 on the ear of the user.

The ear cups 28 have a ledge or protrusion 44 extending outward over the inside surface 29 to aid in supporting the device on the user's ears and to hold the pocket 64 open. Each protrusion 44 has a semi-circular shape and is formed on the upper rim 43 of the inside surface 29 of each ear cup 28. When fabric is used for the ear pads 60, the protrusions 44 work to keep ear pocket 62 on the ear pad 60 held in an opened configuration to facilitate slidable engagement with the top of the user's ear.

Referring to FIG. 3, the ear cups 28 slide into the ear frames 26 and are firmly bonded through interlocking joints (not shown) in the ear cups 28, which slot and attach into keyed joints in the ear frame 26. Alternately, attachment can be accomplished through a known process such as gluing or ultrasonic welding. In the case where an insulating material, such as fabric, is used for the ear pad 60, and when the outer ear frame 26 is fused to the concave ear cup 28, the fabric may be captured and secured between the ear frame 26 and the ear cups 28 to prevent the material from coming off.

The ear protection device 18 is firmly attached to the head 12 through the combination of the interior ear rests 44, with the ear pads 60 and the ear pockets 64 that rest on top of the user's ears, thus supporting the weight of the ear protection device 18. In embodiments where weight is a factor, the headband 22 can be formed to assist in holding the device 18 to the user's head 12. When combined, the ear pocket 64 resting on top of the ear and the resilience of the headband frame 22 can work together to ensure stability in wearing the ear protection device 18. Ideally, the resilience of the headband frame 22 does not tightly squeeze the ear protectors 23 tightly to the user's head 12. Rather, it positions the ear protectors 23 over the ears and against the hear 12 only with enough force to prevent wind from entering the user's ears.

The ear cups 28 have an interior concave shape to follow the raised shape of the user's ear to keep the ear protection device 18 in a comfortable stable position. The ear cups 28 are formed from the same lightweight material used to construct the headband 22 or from a lightweight material such as elastomer that is softer and more flexible than that of the headband 22 so as not to be affected by the individual differences in the shapes of ears and so as to help alleviate the load when ear protection device 18 is worn. Ideally, the ear protection device 18 is formed of a flexible and resilient material, such as polypropylene.

In another embodiment, the ear protection device 18 can include at least one acoustically designed component that facilitates hearing. More particularly, a passive amplifier is provided that facilitates the travel of sound waves through the ear protectors 23 and into the ear, allowing for hearing to be enhanced and minimally obstructed. In one embodiment, the device 18 includes a cover or door 30 formed on the exterior of the ear frame 26 to selectively cover and uncover a hollow interior formed between the ear frame 26 and the ear cup 28. Sound waves are directed through the ear frame 26 and holes 46 formed in the ear cups 28 and into the ear. The door 30 has a concave shape that captures the sound waves and directs them through the holes 46 formed of varying sizes in the ear cups 28.

The door 30 may be mounted in a variety of ways to the ear frame 26. As shown in FIGS. 7 through 8A-E, the door 30 is secured with at least one hinge 32 that is built into the ear frame 26. The design of the hinge 32 enables selective positioning of the door 30 at predetermined degrees of opening (see FIG. 4). The hinge 32 is built into the ear frame 26 and features a cylindrical post 52 onto which the door 30 is attached with at least one U-shaped cut 54 (shown in FIGS. 8C and 8D). The cylindrical post 52 varies in diameter near the top and bottom thereof so as to keep the U-shaped cuts 54 in position and prevent them from sliding. The outer ear frame 32 also features a friction lock 58 that allows the door 30 to stay partially opened, and a positive stop in the form of a nob 56 on the post 52 that enables the door 30 to stay completely open at a set position while preventing the door 30 from being pushed in further than desired.

Within the ear cups 28 there can be provided a housing 36, as shown in FIG. 9, as a means for mounting an acoustical device 90, such as speakers or a hearing aid or amplifier. An electrical cord 92, may be connected to the acoustic device 90, which is fastened in the acoustic housing 36 of the ear cups 28. The electrical cord 92 then passes within a groove (not shown) built into the headband frame 22 so as to hide the electrical cord 92.

In use, the ear protection device 18 is put on an individual's head 12 in the following manner: The user takes hold of the device 18 so as to slightly widen the gap between the left and right ear protectors 23 while sandwiching the head 12 so that the pockets 64 are positioned in alignment over the user's ears.

When the ear cups 28 come into contact with the top side of the ears, the user then releases the ear protection device 18, which has been pushed slightly downwards so that the ear pockets 92 come into contact with and are received over the top of the ears. In doing so, the complete device 18 is positioned on and supported by the ears. The putting on of the ear protection device 18 is then complete (see FIG. 2). If desired, the headband 22 can be formed to urge the ear protectors 23 against the user's head to prevent wind from entering the user's ears.
